Craigslist.org, the wildly-popular classifieds site, made news this weekend when they blocked a contentious portion of their site: the section pitching "adult" services.

The change would have gone unnoticed by most Craigslist users - those who are seeking a roommate, or an antique tractor, or even feedback on their haiku. But those who were looking to buy sex through the site were met with a big black bar over the link, marked “censored." There's been no word from Craigslist on whether the action is a response to criticism and petitions by state attorneys general to close the section, or whether it marks a lasting change. To talk about what this might mean, we're joined by Louise Story, Wall Street and finance reporter for The New York Times.
